Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

n8n-nodes-mopdf

v0.3.0

Published

n8n community node for PDF processing - convert PDF to images, extract text and run OCR

Readme

n8n-nodes-mopdf

Extract text from PDFs, convert pages to images and generate AI-ready output — without any API, running entirely local inside n8n.

Built on MuPDF and Tesseract.js.

Installation

In n8n: Settings → Community Nodes → Install

n8n-nodes-mopdf

Operations

PDF to Images

Renders each PDF page as a PNG or JPEG image.

| Parameter | Default | Notes | |---|---|---| | DPI | 200 | 72 – 600 | | Format | PNG | PNG or JPEG | | Pages | All | Specific pages supported |


OCR

Runs optical character recognition on an image binary.

  • 11 supported languages (German, English, French, Spanish, Italian, Portuguese, Dutch, Polish, Russian, Simplified Chinese, Japanese)
  • PSM modes: Auto, Single Block, Single Line, Single Word, Sparse Text
  • Output format: Plain text or Markdown
  • Optional: word and line coordinates in output
  • Carries over input JSON fields (Keep input data)

Text Extraction

Extracts selectable text directly from a PDF — no OCR, fast.

  • Output formats: Plain text, Markdown, JSON, HTML
  • Per-page or combined output
  • Optional: PDF metadata (title, author, etc.)
  • Optional Text only mode — output contains only the text field, no statistics

Text + OCR Fallback

Tries direct text extraction first. For any page that yields no text (e.g. a scanned page), OCR runs automatically as a fallback.

  • Selectively replaces only empty pages — pages with extractable text are kept as-is
  • Output formats: Plain text, Markdown, JSON, HTML
  • For Markdown format, hOCR is used automatically on OCR pages for better structure
  • Optional Text only mode

Output formats

| Format | Description | |---|---| | Plain text | Clean extracted text | | Markdown | Structure-aware output, suitable for LLMs | | JSON | Raw structured text with bounding boxes | | HTML | Full HTML with layout information |
